With the improvement of people’s living standards, the requirements for food quality and safety are becoming higher and higher. As a new type of food packaging machine, the emergence of external-extraction vacuum packaging machine provides a better solution for food preservation. This article will introduce in detail the use methods and advantages of external-extraction vacuum packaging machines.
1. Use method of external vacuum packaging machine
1. preparations
First, you need to put the food into a vacuum bag and place the opening of the vacuum bag on the vacuum port. Then close the vacuum cap.
2. vacuum packaging
Next, turn on the power switch of the machine, turn on the switch at the vacuum port, and start vacuum packaging. During the packaging process, the machine will automatically withdraw the air from the bag until it is completely vacuum. At this time, the machine will automatically close the vacuum port and start sealing.
3. sealing
When sealing, you need to place the bag mouth in the center of the sealer, then press the button of the sealer, and wait until the light turns on to complete the sealing.
2. Advantages of external vacuum packaging machines
1. Extend food preservation period
The biggest advantage of the vacuum packaging machine is that it can effectively extend the shelf life of food. Because the air in the packaging bag is extracted, the oxygen content of the food is reduced, which can effectively inhibit the growth of bacteria and mold and prolong the shelf life of the food.
2. Prevent food spoilage
The packaging method of the vacuum packaging machine can effectively prevent food spoilage. As the air in the packaging bag is extracted, the oxygen content of the food is reduced, which can effectively prevent oxidation and deterioration.
3. Maintain the nutritional content of food
The packaging method of the external vacuum packaging machine can maintain the nutritional content of food. Since the air in the packaging bag is extracted, the nutritional content of the food will not be lost due to oxidation, so that the nutritional content of the food can be maintained.
4. Improve food safety
The packaging method of external vacuum packaging machines can improve food safety. As the air in the packaging bag is extracted, the oxygen content of the food is reduced, which can effectively inhibit the growth of bacteria and mold, thereby improving the safety of the food.
3. Conclusion
In short, the external-extraction vacuum packaging machine is a very practical food packaging machine, which can effectively extend the shelf life of food, prevent food from spoilage, maintain the nutritional content of food, and improve food safety. When using it, you need to pay attention to correct operating methods to give full play to its advantages.
